Operation Indicator Equipped Model
All the models can be equipped upon request with a operation indi-
cator to facilitate maintenance and inspection.
Because the indicator is incorporated in the terminal protective cov-
er, the dimensions of the limit switch are not affected. In this model,
the lead wire is to be connected to the screw terminal. (A connecting
washer is provided on the tip of the lead wire).
The lead wire can be connected to either the NC or NO terminal.
Operating characteristics are the same as the standard model from
which the operation indicator equipped model is fabricated.
AC Operation
The operating voltage range is from 90 to 250 VAC.
The dimensions are the same as the standard type. The top of the
terminal protective cover is transparent to allow checking the opera-
tion easily.
When placing your order for the indicator equipped, AC-operated
model, add suffix “L” to the end of the model number.
Example:
Standard type:
ZC-Q2255
Indicator equipped type: ZC-Q2255-L
